Abstract
A device that stores a low molecular gas, such as hydrogen (H2), under high pressure includes having an inner shell and at least one outer sleeve surrounding the inner shell. The region between the inner shell and the outer sleeve is connected via at least one valve with a backflow prevention capability to the region surrounded by the inner shell. The valve is thereby formed so that low molecular gas which has diffused through the inner shell can flow back into the inner shell when there are suitable pressure conditions.
Claims9
A device for storing low molecular gases under high pressure, the device comprising:
- an enclosed inner shell;
- at least one enclosed outer sleeve having an inner side surrounding the inner shell and an outer side exposed to an environment outside of the device;
- a connection element having a first side exposed to the environment outside of the device and a second side exposed to an inside of the enclosed inner shell, wherein the connection element is configured to allow filling and removing the low molecular gas from the inside of the enclosed inner shell;
- a backflow prevention valve arranged in the connection element in a region between the enclosed inner shell and enclosed outer sleeve so that it connects the region between the enclosed inner shell and enclosed outer sleeve to the inside of the enclosed inner shell in such a way that low molecular gas that diffused through the enclosed inner shell flows back into the enclosed inner shell under certain pressure conditions.
